i want to do an experimental research to test these null hypothesis;H01: There is no significant difference between the academic achievement of control group and experimental group on pre-test.
H02: There is no significant difference between the academic achievement of control group and experimental group on post-test.
Ho3: There is no significant difference between the academic achievement using cognitive load approach and traditional approach in teaching general science.
H04: There is no significant difference between the academic achievement of control group and experimental group on retention test.how should i teach to both the groups? should only one teacher teach to both the experimental and control groups?or one teacher should teach to the experimentsl group and another to the control group?what will be the best way to control extraneous variables and what will be the theoritical framework of my study?please give me a detailed answer

Answer:
The leaves of certain plants exhibit droplets of water along their margins in the morning. This particularly happens in plants growing in warm humid conditions. A humid environment hampers transpiration while the roots continue to absorb water from the soil. This builds up a big hydrostatic pressure within the plant and “forces out” the excess water directly from the tips of veins in the leaf. Special pore-bearing structures called hydathodes are present on the margins of the leaf to allow this exudation.
